analysis_source Legacy particle size analysis of the gravel, sand and mud fractions of offshore samples, these include folk analysis, phi and half-phi sand analysis and carbonate analysis based on folk fractions and are primarily derived from handwritten sample station data sheets. For a small proportion of the dataset, there is an unresolved issue with weight measurements containing a mixture of grams/percent where only grams should be stored. BGS data input methodologies used in the past between northern and southern parts of BGS vary. The underlying PHI data values are sound except where human error may have occurred. Where the sand PHI weight analysed was a split/fraction of the total sand component of the sample the northern and southern parts of BGS adopted differing data recording methods. The northern part of BGS generally recorded the sand PHI weight for each PHI interval for the actual volume of sample analysed. The southern part of BGS generally took the sand PHI weight for each PHI interval then calculated the percentage of each PHI sand interval and used these values to back calculate the PHI sand weight representative of the total sand which was then recorded in the database.
